Re:Subquadratic – Introducing SubQ 1.1 Small on Tuesday June 16, 2026 @03:53PM (#48560996)
I don't mean to be shady, but there are plenty of details that they did release that show that they don't know what they're doing.

They make comparisons to FlashAttention-2 when FlashAttention-4 has been out (even if they wanted to stick to Hopper class GPUs for whatever reason there's still FlashAttention-3). The two orders of magnitude claim look like they're for prefill not next-token decoding, which is a bit duplicitous. Long context extrapolation experiments typically go well beyond 2x context length. Etc etc etc.

I never said they should have a full public disclosure, but I do think sharing something of substance helps build trust and also get people excited.

Lastly, frontier labs have other incentives than to eek out every dollar and cent. Having the most capable models, not the most cost effective, is of significantly higher priority as OpenAI and Anthropic march towards IPOs. The same is not necessarily true for Google/DeepMind, and one can see from their public releases alone for some of their open weight models that this may be more of a priority for them today.

Ahh cf my comment above. The cost of failure at scale is too high for a major to just take a new architecture/mechanism and implement it, especially because a) most claims papers make aren't rigorously tested and b) plenty of things that work at one scale do not work at the scale on which the labs operate. If they want to get acquired, then they should show that they know what they're doing. Otherwise, it looks sketchy.

I don't think it makes sense from a business perspective to hold off on details as a new lab. OpenAI will not implement new architectural changes unless they've tested the changes themselves internally. Even if someone claims some great innovation, they'd need to do scaling experiments to somewhere between the size of GPT-4 to GPT-5 before they'd decide it is worth it to implement themselves. Plenty of mechanisms that seem to work at one scale do not translate to the next.

Because the cost to OpenAI to make an architectural shift is far greater than the cost to a new lab to try something different, providing details is usually a net benefit for recruiting, building trust, getting acquired, etc. The lack of details is a poor business decision because it makes them seem untrustworthy.

I'm not advocating that they should open source their model, but there is already so much noise in the space and many bad papers that being cagey is a poor strategy for winning over talent, developers, etc.

I don’t understand why this lab is allergic to providing details on what they actually made, especially when Chinese labs are more than willing to share architectural specs/code/kernels (eg NSA/FSA, RAMBa, HISA, DSA LightningIndexer, etc). I don’t doubt that they’ve done something here, but the lack of details makes me default not trust this, particularly when this is the second time that they’ve released a “technical report” that just waxes poetic about the concept.

Well I told the ants they were beautiful and they responded with "ty we blushing". I need more Ant Chat in my life :D
No sadly not :(
The article does a great job of highlighting the core disconnect in the LLM API economy: linear pricing for a service with non-linear, quadratic compute costs. The traffic analogy is an excellent framing.

One addition: the O(n^2) compute cost is most acute during the one-time prefill of the input prompt. I think the real bottleneck, however, is the KV cache during the decode phase.

For each new token generated, the model must access the intermediate state of all previous tokens. This state is held in the KV Cache, which grows linearly with sequence length and consumes an enormous amount of expensive GPU VRAM. The speed of generating a response is therefore more limited by memory bandwidth.

Viewed this way, Google's 2x price hike on input tokens is probably related to the KV Cache, which supports the article’s “workload shape” hypothesis. A long input prompt creates a huge memory footprint that must be held for the entire generation, even if the output is short.

Does anyone know how AI coding fits in with S174? If a person’s “coding” part of the job is primarily running prompts and checking code outputs (quality control and minor reprompting) with the remainder of the time used for other activities, does this count as software engineering?

It seems like an inevitable outcome of this is elaborate system-gaming to mitigate how much employees fall under S174…

Re:Web search on the Anthropic API on Wednesday May 07, 2025 @04:52PM (#43920450)
I think the most interesting thing to me is they have multi-hop search & query refinement built in based on prior context/searches. I'm curious how well this works.

I've built a lot of LLM applications with web browsing in it. Allow/block lists are easy to implement with most web search APIs, but multi-hop gets really hairy (and expensive) to do well because it usually requires context from the URLs themselves.

The thing I'm still not seeing here that makes LLM web browsing particularly difficult is the mismatch between search result relevance vs LLM relevance. Getting a diverse list of links is great when searching Google because there is less context per query, but what I really need from an out-of-the-box LLM web browsing API is reranking based on the richer context provided by a message thread/prompt.

For example, writing an article about the side effects of Accutane should err on the side of pulling in research articles first for higher quality information and not blog posts.

It's possible to do this reranking decently well with LLMs (I do it in my "agents" that I've written), but I haven't seen this highlighted from anyone thus far, including in this announcement.
